WINDER.

To aZZ whom it may concern:

Be it known that I, BURT A. PETERSON, a citizen of the United States, residing at Rockford, in the countyof Winnebago and State of Illinois, have invented certain new and useful Improvements in \Vinders, of which the following is a specification.

This invention relates to winders of the general type disclosed in Patent No. 1,267,- 977 dated May 28, 1918, to Howard D. Colman, wherein a winder-tending mechanism is adapted to travel around the winder and operate upon a plurality of winding units. The traveling mechanism shown in said patent comprises means for measuring or gaging the yarn masses produced by the machine, means'for preventing the, yarn of a reserve supply bobbin from being tied to a full size yarn mass, and means for preventing the reserve bobbin from being transferred to running position. The object of the present invention is to provide acomparatively simple mechanism of this general type which shall be adapted to cooperate with a different type of supply bobbinholder from that shown in said patent. 7

Referring to the accompanying drawings, Figure 1 is a front elevation of a portion of the winder-tending mechanism of a winder embodying the features of my invention. Fig. 2 is a side elevation of the lower portion of the winder-tending mechanism showing the mechanism engaging with a bobbinholder to actuate it, said bobbin holder'being shown in broken lines. Fig. 3 is a fragmentary vertical section taken transversely through the winder-tending mechanism. Fig. 4 is a fragmentary plan section through a portion of the winder-tending mechanism taken in the plane of line 4-4 of Fig. 1. Fig. 5 is a similar view taken in the plane of line 55 of Fig. 1. Fig. 6 is a fragmentary front elevation of parts illustrated in Fig. 4; showing details of construction. Fig. 7 is an under side view of a portion of the winder-tending mechanism. Fig. 8 is a fragmentary elevation of the same. Fig. 9

is a perspective view of one of the parts. Fig. 10 is a rear side elevation of a portion of the winder-tending mechanism.

The embodiment herein shown of the invention is generally similar to the machine disclosed 'in said Patent No. 1,267,977, and

consists of a plurality of winding units arranged side by side for unwinding yarn from bobbins onto tubular cores to form cheeses, and a carriage 89 (Fig. 1) arranged to travel along the series of winding units, said carriage having mechanism for attaching the ends of the yarn on the bobbins to the ends of the yarn on the cheeses, as well as for performing various other operations attending the production of cheeses.

- Each winding unit comprises suitable bobbin-holding means. Herein I have indicated, by way of example, a bobbin-holder (BH, Fig. 2) of the type disclosed in my application Serial No. 323,194, filed September 11, 1919, to which application reference may be made for a full disclosure of the bobbin-holder. It is sufficient to say here that the bobbin-holder comprises a reserve-bobbin pocket and a compartment to contain the bobbin being unwound. The

spent bobbin is discharged from said compartment and the reserve bobbin transferred to said compartment byv a skewer which is actuated by means including a plunger A (Fig. 2) arranged to be depressed by a cam bar on the winder-tending carriage. Said plunger extends through a guide opening 7) which allows lateral movement of the plunger.

Each unit comprises a clamp (not shown) to hold the end of the thread of the reserve bobbin. This clamp may, if desired, be similar to the one fully described in the before-mentioned patent.

Upon the winder-tending carriage is a suitable knot-tying mechanism (not shown) which may, for example, be similar to that shown in said Colman patent and so located as to be carried, in the travel of the windertending carriage, into operative relation to the reserve thread held by the clamp of each winding unit.

Means is provided for detecting the fact that the cheese ofany unit has reached the desired diameter. When such a cheese is reached by the winder-tending mechanism, devices are actuated to prevent the reserve thread from entering the knot-tying mechanism, to prevent the reserve thread clamp holder. The means for preventing the re serve thread from entering the knot-tying mechanism includes two arms 361 and 361, similar to those correspondingly numbered in said Colman patent, which are actuated to deflect the reserve thread out of the path of the knot-tying mechanism as explained in the patent. For this purpose, the said arms are fixed upon a pivot 362, and rigidly attached to said pivot is an arm 185 (Fig. 5) operatively connected with alever 702 which is arranged to be swung, in a manner to be hereinafter described, whenever a yarn container or cheese attains a predetermined size. The free end of the arm 185 is forked to receive a pin 187' that is carried by an arm 675 fixed to a rock shaft 676. Connected to said shaft is a device for preventing the plunger A from being operated. The arm 361 carries a member 360 (Fig. 5) operable, as will hereinafter appear, to prevent the reserve clamp from being opened.

Referring now to Fig. 10: A bar 677 is fixed to the carriage 89 and extends longitudinally of the path of movement of said carriage. The lower edge of the bar is arranged to engage an anti-friction roller A on the plunger A. At the leading end of' the bar 677 is an inclined surface 678 which depresses the plunger sutliciently to cause the spent bobbin to be doffed. Following the cam surface 678 is a dwell surface 679. On the lower edge of the bar 677 is a series of cam surfaces 680, 681, 682, 683 and 68%- adapted to actuate the plunger to place the reserve bobbin in running position immediately after the reserve thread has been tied to the exhausted thread. Extending along the bar 677, beside the cam surfaces 680684, is a dwell surface 685 located at the same height as the dwell 679. Means is provided for switching the roller A away from the cam surface 680 and onto the dwell 685 in case the cheese of that particular unit is full. The switching means comprises a block 686 which is pivoted at one end to the bar 677 at 687. The bar 677 is cut away to form a recess 688 to receive the switch block 686. When the block is swung up into said recess, the lower surface of the block is substantially flush with the dwell surfaces 679 and 685.

The dwell 685 is offset or at one side of the'plane of the dwell 679, as best shown in Fig. 7. In order to guide the plunger laterally from the dwell 679 to the dwell 685, there is inserted in the bar; 677 a plate 689. The edge 690 of this plate is a continuation of the incline 680. The side 691 of the plate 689 extends at an angle with referenceto'the dwells 679 and 685.

Gravity tends to hold the switch block 686 in such position that its lower surface forms a continuation of the surfaces 679 and 680, the switch block having a finger 692 which is arranged to engage a stop pin 693 Means is provided for locking the switch block in such position in order that it shall not yield to the upward pressure of the plunger A. The locking means consists of a latch 69% pivoted to the bar 677 at 695 and notched to engage a lug 696 (Fig. 9) on the finger 692. Rigid with the latch 694: is a crank arm 697. A contractile spring 698 connected to said arm tends to move the notched end of the latch into engagement with the lug 696. Connected to the arm 697 is a link 699 having an elongated opening 700 (Fig. 7) to receive a pin carried by a crank arm 701 (Fig. 2) on the rock shaft 676.

The means for rocking the shaft 676 to unlatch the switch block 686 and swing the thread-deflecting arms 361 and 361 against the reserve thread comprises the lever 702 (Fig. 5) which is mounted on a pivot 703. One arm of the lever 702 carries a pin 701 (Figs. 5 and-10) that lies in a hook 705 on an arm 485. The other arm of the lever 702 is normally held against a stop 706 by a contractile spring 7 07 Alined with thepivot 703 is a pivot 708 (Figs. 3 and 4) on which is mounted an arm 709. The lever 702 and the arm 709 are connected together by a bar 710. Preferablythe lever 702, bar 710 and arm 7 09 are cast integrally to form a rigid yoke member. Mounted on the pivot 708 is an arm 711 carrying a roller 712 that engages a cam 713 on a constantly rotating shaft 223. hen the windertending mechanism reaches a full cheese, the arm 7 09 is connected to the arm 711 so as to be moved by the cam 713 against the tension of the spring 707. The means for thus connecting the arms 709 and 711 comprises a latch 714 (Figs. 3, 1 and 6) pivoted at 715 on the arm 7 09 and having a projection 716 adapted to enter a locking recess 717 in a plate 718 attached to the arm 711. At one, side of the recess 717 is an inclined surface 719. A contractile spring 720 tends to swing the latch into position for the projection 716 to enter the recess 717, and a stop lug 720 on the arm 709 (Fig. 1) serves to limit movement of the latch member by the spring.

The means for preventing the projection 716 from entering the recess 717 until a full cheese is reached comprises an arm 721 (Figs. 3 and 6) arranged to engage a lug 71% on the latch 7 14. The arm 721 is at tached to a horizontal rockshaft 502. A

feeler or gage 505 is adjustably connected The end 506 of the the normal position of the gage being adjustable to correspond with the size of the cheese desired.

When the gage 505 is in its normal position, the arm 721 lies in such position as to prevent the projection 716 from. entering the recess 717 as the recess is moved under said projection by the cam 713. When the gage is raised through contact with a cheese, the arm 721 is moved away from the lug 71%. Consequently when the recess 717 is moved under the projection 716 by the cam 713, the spring 720 places the projection in said recess, thus locking the arms 709 and 711 together. In the continuing rotation of the cam 713, both arms are swung,fthereby causing the arms 361 and 861 to push the reserve thread out of the path of the knottying mechanism, and withdrawing the latch 694: from the lug 696. WVhen the switch block 686 reaches the plunger A of the unit containing the full cheese, said switch block yields to the pressure of the plunger, and the roller A engages the side 691 of the plate 689 and is thereby moved laterally onto the dwell 685. Consequently the reservebobbin is not placed in running position.

lVhen the reserve thread is deflected out of the path of the knot-tying mechanism, the projection 360 (Fig. 5) on the arm 361, which normally opens the clamp in which the end of the reserve thread is held, passes clear of the clamp.

It will thus be seen that when a full cheese is met with, the reserve thread clamp is not opened, the reserve thread is deflected out of the path of the knotter, and the reserve bobbin remains in reserve position. When the winder-tending mechanism has passed the unit, the operator removes the cheese.
